The invention relates to the constructionof spectacles, and has for itsprincipal ob]ect the provision of 'a mounting for the lensesv ofspectacles by which the lenses have flexibility relatively to the bridgemember mounted on or engaglng the nose of the wearer.

. In the construction of spectacles it is desirable that lenses at alltimes shall be in f proper alinement. This is necessary in order thatthe corrective features of the lenses shall be in proper positionrelatively to the wearers eyes to overcome the defects for which thelenses are provided. vHeretofore in the construction of spectacles ithas been the practice to make the lens supports rigid with the bridgepiece. During the use of the spectacles the frame members are liable toget out of alinement making it essential that the spectacles bereadjusted frequently in order to insure proper alinement of the lenseswith the wearers eyes. To overcome this defect in spectacles as atpresent made, the members connecting the rigid bridge and the lenssupports are made resilient, to permit relative movement of the lenssupports on the bridge member, and this is an object of the invention.

' Another object of the invention is the provision of what might betermed-a shock absorber between the rigid bridge and the lenses toeliminate dangerlof breakage of the lenses at the lens clamps inremoving the glasses from. or putting them on the wearers face, orduring handling, this being an incident of the use of the resilientconnection between the bridge and lenses. Furthermore this resilientconnection prevents bending of the bridge in handling the glasses whichwould result in throwing it out of adjustment and altering the relativedistance between the pads, which have been previously fitted vtoproperly accommodate `themselves to the. h

wearers nose.

The invention will be described in detail hereinafter, and will be foundillustrated in the accompanying drawings,'in which:

In the drawings similar reference characters are used to designatecorresponding parts in all of the views.

For the purpose of illustrating the improvements and means forconnecting the bridge member and lens supportsl of spectacles aconventional type of bridge and nose rest is shown in which is a rigidbridge member having downwardly extending arms 2, and joined to nosepads 3 by means of a tubular clamping member 4 receiving the lower endsof the arms 2,'that`are reduced and flattened as shown at 5 to fitwithin the clamping member 4, and joined to a flat'portion 6 of arms 7supporting the nose pads 3, and held together in the usual manner bymeans of a nut and bolt 8. The partshereinbefore described areconventional parts used in the nose pad type of ophthalmic mountings,and in lieu thereof it will be apparent that any other type of rigidbridge structure may be substituted therefor, such for instance as whatis known in the art as a saddle bridge. The lenses A may bev supportedby means of clamp or strap members 9 as shown in the drawings, or inlieu of the clamp or strap members 9 the lenses maybe secured in theconventional frames, but instead of being secured directly to Ithe`bridge member a conas rolled gold, said strap 10 being preferably i00formed in U-shape as best shown in Figures Y 4 and 6, having one of itsends soldered, or

otherwise secured to the lens support 9 while its other end is securedto the nose side of clamping member 4 and at right angles to the ends 5and 6 of the arms-2 and 7 respectively, said clamping member 4 beingprovided with a cut-out grooved portion 1l in which the free end of thestrap 10 is seated, and is securedto the clamping member 4 by the boltand nut 8 heretofore referred to, or by any other suitable means.

As the resilient member 10 is arranged so that it is at right angles tothe arms 2 and 7, as hereinbefore described, the resilience in the clamprelatively to the bridge member and the nose pads, as shown in thedrawings, is in a plane substantially at right angles to the bridgemember, this permittin flexibility of the lenses relatively to the brige member which will prevent distortion of the brid e adjustment duringhandling and the res t'l ant altering of the alinement of the lensesrelatively to the eyes of the wearer, It will be furthermore understoodthat because of this construction adjustment of the bridge member 1 andthe nose pads 3 may be made to suit the convenience of the wearer andthis l adjustment will be permanent and all danger of the alinement ofthe lenses being destroyed by the bridge member and nose pads becomingdistorted during handling is avoided, and that furthermore in whateveradjustment the bridge members and the pads are placed the lenses willalways be in proper osition or alinement relatively to the eyes o thewear er. It will be furthermore understood that the flexibility of thestraps 10 may vary to suit different conditions in different mountin IFigure 7 is shown a mountin including the anchor members or straps 9 1nwhich y the flexible member designated 20 is connect- .the anchor orstrap 9 and extended downwardly as shown at 32 and then curvedlaterallyand upwardly as shown at 33 in a continuous spiral ending witha downwardly;

curved portion 34 turned upwardly as shown at 35 and provided with anend36 to be se-v cured to the clamping member 4'. j

It will be understood that the expressions nose rest and nose-engagingmember as.

used in the claims is deemed to include the part or parts that support`the spectacle from ient element havin the nose of the wearer and mayinclude either or both the bridge and the pads, which parts are adaptedfor permanent adjustment with res ect to each other.
